In 4000 B.C., Babylonians played a board game that was probably the ancestor of chess and checkers. Stone yo-yos were first used in ancient Greece around 1000 B.C. Kites appeared in China around the same time, though historians speculate that they have probably been flown since before recorded history.
The 20th century saw the invention of dozens of much-loved toys as well. Still-popular board games like Tripoley, Sorry and Monopoly have been around since the 1930s, and Crayola Crayons are more than 100 years old!
